I picked up a XM:Magneto immediately after playing the Wolverine on location. That was when it was new and has unfinished code. With a little patience, and a few code updates installed later, I can say that XM is the game that I have had the longest in my collection. I just keep going back to it...
The time came to sell it to make space for my Rob Zombie pin.... Did not want to give it up. I solved the problem be rearranging the space in my basement and was able to free up space for 3 additional pins (comfortably... comfort counts in my space).
X-Men stays.
